STARDEX Deliverable D-16 Partner Contributions - Recommendations on the more robust statistical and dynamical downscaling methods for the construction of scenarios of extremes

This deliverable focuses on the specific characteristics of each downscaling method.
The following information is provided for each method:
• Summary
• STARDEX deliverables and papers
• Overall assessment
• Robustness criteria
• Application criteria

A distinction is made between direct methods in which seasonal indices of extremes are
downscaled and indirect methods in which daily time series are generated and the seasonal
indices then calculated from these.

Precipitation related indices of extremes : pq90 90th percentile of rainday amounts (mm/day),
px5d Greatest 5-day total rainfall, pint Simple daily intensity (rain per rainday),
pxcdd Maximum number of consecutive dry days,
pfl90 % of total rainfall from events > long-term 90th percentile,
pnl90 Number of events > long-term 90th percentile of raindays,

Temperature related indices of extremes:
txq90 Tmax 90th percentile (ºC)*, tnq10 Tmin 10th percentile (ºC)**,
tnfd Number of frost days Tmin
